Preparation Strategy

To maximize your chances of success, focus on the following preparation tips:

• Begin with your chosen discipline since Part II contributes to the majority of the score.
• Concentrate on subjects rather than just topics for more effective revision.
• Engage in short daily practice for aptitude; this will help you stay consistent.
• Factor in the negative marking while answering questions; be confident in your eliminations.
• Practice with full-length mock tests under the 2-hour time constraint to develop speed.
• Create a formula sheet for quick reference on numerical subjects and revise commonly tested areas.

Common Mistakes to Avoid

• Neglecting to review the entire syllabus.
• Underestimating the importance of the General Aptitude section.
• Failing to time your practice tests effectively.
• Not familiarizing yourself with the exam format before test day.
• Ignoring previous years’ question papers for preparation.
